Basic Compass with Key Ring.
This thing will point North so you will always know where North is.

Usage instructions:
If you want to find east, it is about 90 degrees to the right of the red arrow.
If you want to find west, it is about 90 degrees to the left of the red arrow.
If you want to find south, it is about 180 degrees to the opposit side of the red arrow.
If you match the red arrow position with the "N" sign, it tells you where East, west and south is.
